E08Y HI8PA AND DBOP-WOEM. 



fiinii>Iu'(l wilh a pair of very short lioklors, or prop-legs. The male clirysalis is a 

 little more than six-tenths of an inch long, of a dark brown color, and exhibits the 

 sheaths of the wings, and limbs of the future moth, which escapes from it toward 

 the end of September or early in October, immediately before which the chrysalis 

 forces itself half way out of the lower end of its case. The female chrysalis is nine- 

 tenths of an inch long, or more, of the same color as that of the males, but without 

 any vestige of wing-sheaths or limbs. There is a prominent ridge over the fore part 

 of the body. When the included female is matured, the skin of the chrysalis splits 

 at the ridge, so as to form an opening in the shape of the letter T, and through this 

 opening the approaches of the male moth are made, the female remaining all the 

 while not only enclosed in her pod, but also encased in the skin of the chrysalis. In 

 this skin, also, she lays her numerous eggs, gradually withdrawing lier emaciated 

 body as she fills the pupa skin, and finally closing the upper part of the skin with a 

 thick layer of fiiwn-colored down, stripped from her own body. Having finished her 

 labors, she crawls out of the pod, entirely shriveled up, drops off and dies, or more 

 rarely perishes at the mouth of her pod. She is found to be entirely destitute of 

 wings, and her legs are extremely minute, and resemble little tubercles. The male 

 moth, on the contrary, is fully provided with wings and limbs. Its body, which 

 measures rather more than half an inch in length, is covered with long blackish-brown 

 down. Its wings are semi-transparent, and are very scantily clothed with blackish 

 scales, which are thickest on the margins and veins. The white spot, represented by 

 ^Ir. Aebot on the fore wings of his figure, is entirely wanting in all the males that I 



have seen. The antenna? are curved at the 

 tips, and are doubly feathered from the 

 base to beyond the middle. The tongue is 

 not visible. The wings expand one inch 

 i*-*^ //J-,-*:, and one-tenth, or more. The male moths 



are very impatient of confinement, and keep 

 in constant motion, which renders it very 

 difficult to obtain perfect or unrubbed speci- 

 mens. The eggs remain secure in the shell 

 "^\ ^^?:?)M^' ^^ '^^^ ^'^ ^^^ female chrysalis, enclosed in 



the suspended pods, through the -winter, 



and are hatched in the spring when the 



^ : ' %l\^ trees are well clothed with leaves, upon 



which the little worms, having left the 

 pods, immediately disappear, and each one 

 begins to cover its tender body with a silken and leafy case. The figures represent 

 one of the pods or cocoons, suspended by a twig, when the insect has prepared for 

 its final transformation ; also a male moth, both of the natural size.
